.8 it represents .80 cents. rather than .08 which would represent 8 pennies
Let's do 51 and 52.
51. The contrapositive has the same truth value as the original statement. That's opposed to the converse, which may or may not be true independent of the original statement.
The contrapositive of IF P THEN Q is IF not Q THEN not P. They're equivalent. Here that's If the cat is not female then it is not tricolor.
Answer: C
52.
For the statement to be true, the exponent must be zero:
Both positive 2 and negative 2 have a square of 4.
Answer: K
By the way, usually we assume 
so the restriction that 
isn't really necessary. Think of the definition of a polynomial or the binomial expansion:
For these common equalities to work when 
we need to define
Answer:
0.670. M
Step-by-step explanation:
Molarity can be expressed like this:
molarity
= number of moles
/volume (L)
We know the volume, which is 2.37 L
, but we need to find the number of moles. We can do this by dividing 67.3 g by the molar mass of L
i
C
l
:
number of moles =
mass of sample
/molar mass
number of moles = 67.3 g
/(6.94 + 35.45) g/mol =
67.3 g
/42.39 g/mol
number of moles = 1.59 mol
molarity
=
1.59 mol
/2.37 L
= 0.670. M
4(7+3)
Step-by-step explanation:
GCF is Greatest Common Factor
One Common Factor of 28 and 12 is 2 to give 14 and 6
There is an additional common factor between 14 and 6 (which is 2) to give 7 and 3
There is no common factor between 7 and 3
To get the Greatest Common Factor, we multiply the derived common factors 2 and 2 above
2 * 2 = 4
Therefore the correct choice is
4(7+3)

Answer:
The answer is 6
Step-by-step explanation:
All you have to do is take 8x-4 and then combine it with 6x+8 like this...
8x-4=6x+8.
Then you have to add 4 to 8 and you will get 12.
Then you subtract 6 from 8 and get 2. So your equation will look like this...
2x=12
Then you divide 12 by 2 and you get 6 because 6 x 2 is 12.
HOPE THIS HELPS!!!!!!
